SUPPLEMENTARY INFORMATION: The Union Pacific Railroad has requested a temporary deviation from the operating schedule for the swing span bridge across the Calcasieu River, mile 36.4, at Westlake, Calcasieu

Parish, Louisiana. The swing span bridge has a vertical clearance of 1.07 feet above mean high water, elevation 3.56 feet Mean Gulf Level in the closed-to-navigation position.

In accordance with 33 CFR 117.5, the bridge currently opens on signal for the passage of vessels. This deviation allows the swing span of the bridge to remain closed to navigation from 8 a.m. through 5 p.m. with an opening for the passage of vessels from 12 noon to 1 p.m. on the following Thursdays: June 2, 9, 16, 23, and 30, 2011.

The closures are necessary in order to remove and install the structural steel, new gear motors, and shafts at both ends of the bridge and the center pivot pier. This maintenance is essential for the continued operation of the bridge. Notices will be published in the

Eighth Coast Guard District Local Notice to Mariners and will be broadcast via the Coast Guard Broadcast Notice to Mariners System.

Navigation on the waterway is minimal at the bridge site. The very limited commercial traffic at the bridge site consists of commercial tugs with tows. There are only two companies that transit above the bridge. The bridge will be able to open for emergencies if necessary.

There are no alternate waterway routes available. Based on experience and coordination with waterway users, it has been determined that these closures will not have a significant effect on vessels that use the waterway.

In accordance with 33 CFR 117.35(e), the drawbridge must return to its regular operating schedule immediately at the end of the designated time period. This deviation from the operating regulations is authorized under 33 CFR 117.35.

Dated: May 9, 2011.

David M. Frank,

Bridge Administrator.
